Fix optimizedTNT entity behaviour

[altrisi]

Fixes #616

This is basically because in 1.16 snapshots the explosion code changed to not be eye height only for TNT.

I don't know if this fully fixes that or if it produces any other bug. I've just tested that it fixed visually (and in the end pos in the tnt logger) the specific case in the issue. I'm not an expert in explosion code. Please test.

Very likely that's the problem. Optimized TNT code has this problem that is a rewrite, so small details like that will pass unnoticed.

Please @Fallen-Breath grab the proposed fix from https://github.com/gnembon/fabric-carpet/pull/617/checks (download artifacts) and confirm it works as in vanilla.

just finished a quick testing in the wdl in #616 and in my 360ftl heavy cannon in 1.16.4 with normal config and maximum firepower config and it worked well. tho i tested with other mods but i think this issue is solved

Actually, I think the change was to fix TNT rendering in soulsand, and then this had to be added to prevent a bug that caused stacked TNT to jump, but yes, TNT jumping.

BTW just for relating: Relates to CaffeineMC/lithium#66. Else I wouldn't have known the reason for this.
